Great Family Meals

Submitted by Volunteer Mom - 11/13/2015

This cooktop is the 20 year newer version of the one it is replacing. We literally wore the old one out, and loved it so much we bought another one. Never had to have it serviced even once. Especially like the downdraft. No need for a hood. We also ordered the griddle accessory. It is the perfect cooktop for weekly family meals, holidays, and Saturday morning feasts!
